How to: Add Report Server Content Types to a Library (Reporting Services in SharePoint Integrated Mode)
Reporting Services provides predefined content types that are used to manage shared data source (.rsds) files, report models (.smdl), and Report Builder report definition (.rdl) files. Adding a Report Builder Report, Report Model, and Report Data Source content type to a library enables the New command so that you can create new documents of that type.
To add content types to a library, you must be a site administrator or have Full Control level of permission.
